Book Description
The National Marine Fisheries Service (NMFS) and the Bonneville Power Administration (BPA) are involved in a project to evaluate the feasibility of re-establishing anadromous salmon runs to Cle Elum Lake in the Yakima River Basin of Washington state. Historically, the Yakima River system supported large runs of anadromous salmonids that contributed significantly to the Columbia River harvest. Habitat destruction and overfishing drastically reduced run abundance prior to the early 1900s. Salmon runs were eliminated from upper reaches of the Yakima River Basin with development of irrigation storage reservoirs without fishways in the early 1900s. The goal of the NMFS/BPA project is to determine if it is feasible for anadromous salmonids to recolonize the habitat above Cle Elum Dam under the present format of irrigation water withdrawal from the reservoir. The primary concern is whether anadromous fish can successfully exit Cle Elum Lake and survive downstream passage through the Yakima and Columbia Rivers to the ocean.

Book Description
The focus of this research was to study the feasibility for anadromous salmonids to recolonize the habitat above reservoirs in the Yakima River without disruption to irrigation withdrawals. A primary concern was whether anadromous fish could successfully exit reservoirs and survive downstream passage through the Yakima and Columbia Rivers to the ocean.

Book Description
In 1986, a multi-year project to evaluate the biological feasibility of reestablishing anadromous sockeye salmon (Oncorhynchus nerka) runs to Cle Elum Lake in the Yakima River Basin was established between the Bonneville Power Administration (BPA) and the National Marine Fisheries Service (NMFS). This program involves the capture, spawning, and rearing of disease-free donor stock in 1987 and 1988 and assessment of juvenile outmigration and survival from Cle Elum Lake in 1989 and 1990. Work in 1987--1988 involved collection of adult sockeye salmon from the Lake Wenatchee run and incubation and rearing of progeny as donor stock. In July 1987, 263 adults were captured at the Dryden fishway on the Wenatchee River and transferred to net-pens in Lake Wenatchee. Adults were held approximately 90 days and spawned, and the eggs were transferred to a quarantine hatchery. Pre-spawning survival was 95.1%, and all spawners were certified as being free of Infectious Hematopoietic Necrosis (IHN) and other replicating viruses. Egg viability averaged about 40%; however, eyed egg to hatch survival was over 99%. Juveniles are being reared in quarantine, and survival to date is about 92%. The NMFS currently has over 131,000 fry (0.7 g average weight) in culture. Fry have been certified twice (at 0.12 g and 0.25 g average weight) as being free of IHN and other replicating viruses. Viral certification will continue throughout rearing. 13 refs., 4 figs., 3 tabs.
